Rogers, Startex, S.C., assignor to Quality Textile industries, inc, Spartanburg, S.C., a corporation of South Carolina Filed Jan. 25, W52, Ser. No. 168,656 20 Claims. (Cl. NZ-55.1)

My invention relates to improvements in textile machinery and particularly to so-called pickers, or other machines, in which a somewhat compressed fibrous lap of say cotton or the like, is further compressed and Wound into a compressed cylindrical package.

In the case of prior art machines for this purpose, as they existed prior to that disclosed in the William F. Lee et al. application Serial Number 67,374, filed Nov. 4, 1960 now Patent No. 3,105,356 much time is lost in (1) removing a completed lap package therefrom; (2) depositing a lap arbor or pin in position for the formation of a succeeding package thereon; and (3) in restarting the machine. The machine of said Lee et al. application materially improved the lost time situations as to (l) and (2) supra, by the provision of improved machine frame-provided cheek plates at opposite ends of the lap package that is being formed. These Lee et al. cheek plates, by providing forward top edges inclined downwardly and rearwardly to their arbor-receiving seats, facilitate removal movement of a completed lap package over the adjacent forward end of the machine frame; and enable an arbor for a succeeding package to readily roll rearwardly into the cheek seats for the start of the next package. I

It is therefore the primary object of the present invention to further improve the machine of the Lee et al. application, and for that matter, other lap Winding machines, by providing means which may be readily incorporated therein for automatically restarting the machine for the formation of a succeeding lap package as soon as the arbor therefore is in its initial package building location, whether or not check plate-provided seats as such are provided.

Invention also resides in certain novel features of construction, combination and arrangement of the various parts, including means associated with the machine drive control lever and elements of its knockoff means for actuating said lever to its operative drive position.

Various other objects and advantages of the invention will be readily apparent to those versed in the art upon reference to the drawings in connection with the related descriptive matter.

In pursuance of statute requirements a now preferred example of the invention is dealt with herein. However, same should be considered as merely illustrative rather than limitative, since it will be obvious to knowledgeable persons in the textile field that my inventive concept is susceptible of various changes and modifications within the spirit and scope of the subject matterclaimed hereinafter.

PEG. 9 is a sectional detail view of the lifting means for the pawl of FIGS. 1 and 7.

Referring to the drawings, my invention is shown ap plied to the lap winding end of a familiar type cotton picker which includes a frame It) on which are rotatably mounted the usual pair of fluted lap package forming and supporting rollers 12 and 14 in closely adjacent parallel positions. The rollers 1'2 and 14 are provided with gears 13 and 15, respectively, by which they are positively driven by any suitable driving means (not shown) through a pulley 2t) mounted on shaft 21 which latter drive gears 13 and 15 through gears 22, 24 and 26 as indicated in FIG. 3.

In the art machine referred to, lap 16 of textile fibers supplied by conventional opening and picking mechanism, not shown, passes over the rear roller 14 and is compressed and wound up into a compressed cylindrical package 17 on a lap arbor or pin 1% overlying said rollers 12 and id, and frictionally rotated thereby.

In the operation of the machine, end portions of the lap arbor or pin 18 rotatably engage in inverted U-form bearings 28 of heads 29 for movement in a vertical plane substantially perpendicular to the plane of the axes of rollers 12 and 1 and midway between said axes. Each bearingproviding head 29 is mounted on the upper end of a rack 36 which is siidable up and down in a substantially vertical track 32 on frame it) (see FIGS. 3 and 4).

In order to maintain the arbor receiving head bearings 28 at equal distances from the axes of rollers 12 and 14 as the lap arbor it; rises due to the increasing size of the lap package 117, a positive mechanical connection is provided between the arbor bearings 28, comprising pinions 34 mounted on a common shaft 35 engaging racks 30. Thus any vertical movement of one bearing providing head 29 will be transmitted to the other head 2?, ensuring equal movement of said bearing providing heads and at all times maintaining the axis of arbor 18 parallel with the axes of rollers 12. and 14. By reason of this, the lap package 17 Will be compressed to a constant thickness widthwise of said lap and ensure the formation of the necessary cylindrical package 17.

As the lap package builds, and the end portions of the lap arbor or pin 18 rise from the seats 31 which are provided by the usual cheek plates 33, they are'sustained against rearward movement by the upstanding cheek plate provided shoulders 35 which are extensions of the rear walls of seats Sll. v 7

It should be noted here that the cheek plates 33 are dealt with in the aforementioned co-pending application of William F. Lee et al., and that they provide the downwardly inclined forward top edges 33a which communicate with the seats 31. Thus, as shown,.a pin Ida for a succeeding package 17 which is supported on said edges 33a will make a beneficial compressing, or ironing, engagement with the package 17 being built. Then after the package 17 is removed, the secondpin or arbor 18a simply rolls into cheek seats 31 for the start of a succeeding lap package 17. The check plates 33 have J- form forward terminals 37 for the support of a reserve pin or arbor 18, not shown. k

' Referring back to the art machine as herein illustrated,

the pressure between the lap arbor or pin 18 and the of its piston shaft 44 is constituted as a rack 44a engaging a pinion 45 on shaft 36.

The fluid motor 40 has a casing 42 and a piston 44b which forms in said casing a rear chamber 46 and a forward chamber 48. Lines 50 and 52 are provided to connect said chambers 46, 48 to a conventional four-way valve 54 which is supplied with air (or for that matter, fluid) at suitable pressure by line 62, a reducing valve 60 and a line 58 between said reducing valve and said four way valve. Operation of the four-way valve 54 is controlled by the upwardly biased foot treadle 56 to normally connect line 52 and the forward chamber 48 of fluid pressure motor 40 to the fiuid under pressure in line 58 to normally maintain the arbor bearing-providing heads 29 in their lowermost position.

In the art machine the treadle 56 of the four-way valve 54 is arranged to be automatically operated by a knockoff mechanism which differs in certain details from that shown, to raise the bearing-providing rack heads 29 when the lap package 17 has reached a desired size so that the lap package may be removed from the machine.

However, I have made improvements in the usual treadle 56 operating means, as will be hereinafter explained.

The knockoff mechanism, to be presently described, is further arranged to interrupt the drive connection to the fluted lap package supporting rollers 12, 14 and to the usual calender rolls (not shown) which compress the lap 16 prior to its delivery to rollers 12 and 14- and lap arbor 18. The knockoff arrangement is such as to break the lap 16 and effect the winding of the broken end on lap package 17.

The Drive Interrupting Means of the Prior Art (see FIGS. 1 and 2) Referring to FIGS. 1 and 2, the end of the power supply shaft 21, on which pulley 20 is mounted, is pivotally mounted on the frame 19 in the usual self-aligning hearing, not shown. The opposite end of said power supply shaft 21 is rotatably mounted on a lever 72, said lever 72 being pivoted on a stud 73 on frame 11 (see FIG. 2). A gear 74 mounted on shaft 21 adjacent said lever 72 is provided to engage a gear 76 for driving the usual calender rolls (not shown), said gear 76 having its shaft rotatably mounted in the usual frarne-provided bearing (not shown).

The gear 78 concentric with and driven by gear 76 drives a gear 80, said gear 80 being mounted for swinging movement by means of an upstanding L-form post 82 which is pivoted intermediate its ends as at 83 to an exterior side of frame (see FIGS. 2 and 4). Gears 78 and 80 are provided with co-acting hunting-teeth 84 and 86 so that when hunting-tooth 84 on gear 78 contacts tooth 86 on gear 80, said gear 80 and its carrier post 82 will be swung counterclockwise about pivot 83 (FIG. 2) away from gear 78 and against the action of coil spring 81. Spring 81 has one end connected (81a) to post 82 and the other end to frame-carried pin 81b. Upon counterclockwise rocking of post 82 (FIG. 2) the usual connections 88, 88a, 88b between the foot end of post 82 and the vertically pivoted finger 90 actuates the latter outwardly to release the conventional knockoff lever 91.

The knockoff lever 91 is pivoted as at 92 to frame bracket 93 and has the shoulder 91b which supports the gear-carrying lever 72 in its upper or machine drive position. Thus, when kickoff lever 91 is actuated outwardly, lever 72 drops in the bracket provided guide slot 93a to disconnect gears 74, 76 and the machine stops. A pull-down spring 72x is connected. to levers 72 and to frame 10 (see FIG. 2).

In the art machine, and here, the knockoff lever 91 has the inwardly extended lower end and the weight 91a thereon tending to actuate it inwardly to support lever 72. There is also here provided the usual pivoted link connection 94 between lever 72 and the inner end of foot pedal 95 which is fast on shaft 96 which is journalled in the floor or base supported bearing unit 95b. Foot pedal shaft 96 terminates in the usual crank 96a, but instead of depressing the air valve control pedal 56, as in the prior art, to directly effect elevation of the bearing provided heads 29, said crank 96a participates in the control of the bearing heads 29 in a different way which will now be explained.

T he Novel Pawl and Ratchet Assembly Relation to Air Control Pedal 56 (FIGS. 1 and 5) As shown in FIG. 1, and in greater detail in FIG. 7, the crank 96a has the collar 96x inwardly of its free end and also crank 96a has loose thereon the pawl 97 which is located just outwardly of collar 96x. The tooth end of pawl 97 plays over the teeth of a ratchet wheel 93 which is fast on a shaft 99 which has a crank end 99a overlying the air valve control pedal 56 of FIG. 1. This ratchet wheel shaft 99 is journalled in the bearings 100 of a floor-supported unint 102. A spring 104 (FIG. 7) is anchored to pawl 97 and to an adjacent collar 106, fast on the outer end of crank 96a so as to normally urge the tooth end of pawl 97 to engage the teeth of ratchet wheel 98. The pawl 97 also has the lateral stud 97a adjacent its tooth end.

Automatic Stopping of the Machine and Raising of Arbor Bearing Heads 29 Upon Package 1 7 Completion (FIGS. 1, 2 and 5 As shown, the machine is in operation but the hunting teeth-of gears 78, -will shortly rock the post (82) carried gear 80 about post pivot 83 (FIG. 2) and away from gear 73. Such movement of the gear carrying post 82 acts through finger to actuate knockoff lever 91 outwardly and allow the drive gear-carrying lever 72 to drop to disengage gears 74 and 76. Downward movement of lever 72 is accelerated by pull-down spring 72;: (FIG. 2). Such movement of lever 72, in addition to stopping the machine, effects depression of the air valve controlling pedal 56 of FIG. 1 to raise bearing heads 29. There is a novel means including crank 99a (FIGS. 1 and 5) for the position control of the upwardly biased pedal 56 and same will be presently described.

When the machine is operating with the air valve control pedal 56 up the crank end 99a of the ratchet wheel shaft simply rests on pedal 56 and exerts no down pressure thereon, as will be hereinafter explained.

However, when the knockoff lever 91 is actuated outwardly manually or by finger 90 (FIG. 2) to effect disengagement of gear 74 from gear 76 to stop the machine, the dropping of lever 72 acts through link 94, pedal and its crank shaft 96, 96a to actuate the crank 96a and pawl 97 rearwardly and downwardly. Thus, pawl 97 functions to turn ratchet wheel 93 to cause its crank 99a to depress the valve control pedal 56 to elevate bearing heads 29.

With the bearing heads 29 elevated the lap package 17 can be rolled forwardly over the next-to-be-used arbor, or pin 18a and over the forward end of the machine. This permits pin 18a (FIG. 1) to roll down the inclined top cheek edges 33a and into the cheek-provided seats 31 to restart the machine and to commence the building of the next lap package on said pin or arbor 18a through means which will now be described.

The Arbor 18 Operated Means for Restarting the Machine (FIGS. 1, 2, 5 and 6) which is pivoted as at 112 to the upper end of the depending link 114 whose lower end is pivoted at 116 to the forward end of a rearwardly extending lever 117. As

shown in FIG. 2, the rear end of lever 117 is pivoted at 118 to the inner side portion of the frame 161.

Intermediate its end the lever 117 provides the slot 119 for the pivot stud 12-0 (FIGS. 1 and 6) which is carried by the upstanding vertically slidable post 122 working in the guideway 125 of the guide member 124- of FIGS. 1 and 5. This guide member 124- is secured to the ratchet wheel carrying unit 1132 by side cleats 126 extending rearwardly from the latter. These cleats 126 are slotted to receive bolts 128 whereby the guide member 124 can be adjusted toward and from the ratchet wheel 98. The forward wall of the guide member 124 has the slot 131) through which projects the post-carried latchform lug 132 which latter, when the arbor operated lever 108 is in the FIG. 2 position, will be disposed under the stud 97a of the pawl 97, as will be presently explained.

As shown in FIGS. 5 and 6, a backing plate 134 in guideway 125 and backed by a spring 136 which is secured by stud 133 normally maintains lug 1312 projected through guide slot 130.

Bearing Heads 29 Lowered Before Machine Started It is important that the bearing providing heads 29 be lowered approximately to the FIGS. 1 and 2 position before the machine is started. Therefore, this head lowering is effected first. Thus, when the replacement arbor 18a depresses the end of lever 1% to raise link 114 and lever 117 along with post 122, the latch lug 132 engages the pawl stud 97a (FIGS. 7 and 9) and lifts the pawl .37 to disengage it from the teeth of the ratchet Wheel 98.

The above referred to lifting of pawl 97 admits of upward movement of the crank end 9% of the ratchet Wheel shaft 99 under the influence of the upwardly biased valve control pedal 56. Upward movement'of pedal 5% acts through valve 54, as heretofore mentioned, to lower the bearing-providing heads 2-9 to arbor-engaging position of FIGS. 1 and 2 through the action of the piston rack 44a, shaft 16, rack bars 3d, etc. As post 122 continues upwardly the pawl stud 97a disengages from post lug 132 and pawl 97 drops back into engagement with the teeth of ratchet wheel 98.

While shaft 36 is rotating to lower the bearing providing heads 29 throughithe action of pinions 45 and rack bars 30 (FIG. 4), novel cam means on the shaft 36 is approaching a position with respect to lever 72 which will effect raising of said lever 72 to start the machine and permit the knockoff lever 91 to resume its lever 72 supporting position of FIGS. 1 and 2.

The Cam Means 165 for Resetting Starting Lever 72 (FIGS. 2 and 5) In carrying out the invention, the piston-operated con trol shaft 35 for the heads 29 is elongated, as shown in FIGS. 2 and 8, to provide the end 36a, on which is keyed a pinion 140. This pinion 140 meshes with gear 142 which is fast on stub shaft 144 which is journalled in upstanding bearings 146 and 148. These bearings 146 and 148 are suitably secured to the bight portion 148 of a generally inverted U-form bracket having depending legs 152 and 154. Leg 152 of said. U-form bracket 151i is bolted as at 156 to the side of the machine frame 111 and the longer leg 154 is bolted at 158 to the upstanding support 160 having the base 152 which is secured as at 164 to the floor or other supporting surface.

Secured adjacent the inner end of the stub shaft 1M- is the cam 165 which is disposed in plane with the lever 72 and below the latter. The ratio of gears 1411 and 142 is such that by the time shaft 36 has'lowered the bearing providing head members 29 to the FIG. 1 position, the cam 165 will have elevated lever 72 to its FIG. 2 position to re-start the machine through engagementof the levercarried gear 74 with gear 76. At the same time knockoff lever 91 assumes its inward FIG. 2 position wherein its notch 91b (FIG. 1) supports lever 72 to retain gear 74 in engagement with gear 78. It will be understood that spring 31 (FIG. 2) rocks post 82 to re-engage gears 80, 78 as soon as hunting teeth 84, 86 disengage.

The Depressing of the Valve Pedal 56 by Meansdirectly Corrected t0 Knoekofi Lever 91 for Emergency Stopping of the Machine (FIGS. 1 andZ) For emergency stopping of the machine, the weighted end 91a of the knockoff lever 91 has the pivot connection a with the adjacent end of a rock lever 166 which is pivoted 168 to a bearing bracket 169 which latter is secured to the inner surface of one end wall of the frame 141 as shown in FIG. 1. The outer end of the rock lever 16% has the downturned portion 167 providing the foot 171) which, when the knockoff lever is in its operative lever 72 supporting position shown in FIG. 1, will be elevated above the valve control pedal 56.

in the normal operation of the machine, which is to say, the stopping of same by engagement of the huntingteeth 84, of gears 78 and 8d, the knockoff lever 91 is not moved outwardly far enough for the foot portion 171) of rock lever 166 to engage and depress the valve control pedal 56 to elevate the bearing providing heads 2?. However, when the machine is to be stopped as in the case of an emergency, the knockoff lever 91 will be pulled outwardiy to its outward limit against the action of weight 91a and a spring 1'72; and this causes sufficient rocking of lever 166 to cause its foot to engage and depress pedal 56 to elevate heads 29. As air valve pedal 56 is thus depressed, the crank end 99a of the shaft 9 of ratchet wheel his drops down with said pedal 56, and the engagement of paw} $7 with the ratchet wheel teeth will hold the crank end 99:: of shaft 99 in lever-depressing position. When the operator releases the knockofi lever 91, its weight 91a and the spring 172 actuate it against the side of the now lowered lever '72 so as to be ready to move inwardly to support the latter when it is raised by cam 155. The foot 170 of lever 166 is, of course, lifted away from air valve pedal 56 by the action of weight 91a and spring 172 immediately the operator releases knockoff lever 91.

It will be understood that as the lap package 17 builds and arbor 13 rises, the forward end of the arbor-operated lever 108 gradually drops so that the weight of link 114 and lever 117 actuates post 122 downwardly in its bearing 124 by reason of the pin and slot connection 119, 120 between said post and lever 117. When the upwardly slanted bottom of post lug 132 engages the pawl stud 97a, the post 122 and its spring backed backing plate 134 is simply rocked rearwardly in guideway 125, which latter is oversized in a depthwise direction as shown. This permits post lug 132 to resume its starting position below pawl stud 17a so as to be ready to lift the pawl 97 the instant a replacement arbor 18a drops into the cheek provided seats 31.

From the foregoing it will be evident that my invention is readily applicable at but moderate cost to known types of lap forming machines to make them automatic in operation and without substantial modification of same.
